It is the latest Kernel 5.8.0-50-generic which makes the problem. It includes a first Patch from December, which makes things even worse for Kodi. A second Patch from 01.02., which notes the problem with Kodi and fixes it, didn't make it into the 5.8 Ubuntu-Kernel.
I upgraded the Server to Ubuntu 21.04 with Kernel 5.11 and the problem disappeared.
I have read several similar reports since February. It seems to be a kernel regression. See also here.
My suspect is that Ubuntu has backported this to my kernel 5.8.0-49-generic which was installed yesterday.
The question is why does the problem not occur when Kodi is running on a Ubuntu machine?
I have exactly the same experience since yesterday. Nothing has changed, my NFS server is Ubuntu 20.10.
Yesterday I suddenly had a lot of green artefacts when playing any movie. I use NFS since years without problems. The NFS server is my Ubuntu 20.10 Desktop machine.
I switched to another client (Nvidia-based HTPC with Ubuntu 20.04.), also using NFS, and there were no problems with Kodi playback.
Today I tried the latest 10.0 nightly build and have the same experience. Playing via SMB works, playing via NFS only with artefacts. I attach the log.
If it were a network or server problem I would assume that this should also effect other clients. So I have no idea what is going on there.
Did HD also work? I read that under Linux only SD is possible.
Is it possible to watch Amazon Prime videos on a Raspberry Pi 2 with current stable LE 9.2? I couldn't find any information in this forum, and also no add-on in any repository. Looking with Google, I find references to a Sandmann79 repository. Does this still work?
should I open a ticket?
After I read the announcement for 9.2.0
I replaced my Raspi 2 with a new 4B. But it is unusable. The video is stuttering and I see tearing effects. I play 1080p24 Movies (h264) with 24Hz and the TV switches correctly to this mode.
Here is a debug log:
The guys at OSMC seem to be less euphoric:
As the device is new and MMAL is being deprecated from Kodi, we need to support V4L2/GBM. This is still a work in progress by Raspberry Pi
In the interim we will support software decoding. It will be a long time (at least a year) before hardware video acceleration is working well using this stack.
(This was end of October 2019.)
So what is the current status of Raspi 4 support? Should it play 1080p h264 as good as the Raspi 2? If so, why do I experience these problem?
